The test result is intended to be used in conjunction with clinical evaluation as an aid in the risk assessment of acute kidney injury in the critically ill. The NephroCheck Test is indicated for prescription use only.

Using the NephroCheck Test Kit

The NephroCheck Test System is a single-use cartridge designed to detect biomarkers of acute kidney injury, TIMP-2 and IGFBP-7. The test provides results in 20 minutes.

The test procedure involves the operator applying a fresh or thawed clinical urine sample (mixed with labeled fluorescent conjugate) to the NephroCheck Test Cartridge, then inserting the test cartridge into the Astute140 Meter for incubation, reading, result calculation and result display.

Each NephroCheck Test Cartridge contains RFID cards to ensure kit expiration date and lot-specific information is downloaded. Each cartridge also includes two detection zones (one positive and one negative control) as procedural controls that are run automatically with every sample to confirm that the NephroCheck Test procedure is performed correctly.

The NephroCheck Liquid Controls Kit

The NephroCheck Liquid Controls are two levels of external controls used for the quality control monitoring of the NephroCheck Test System. Good laboratory practice suggests that the NephroCheck Liquid Controls be tested:

The Astute140 Meter Kit

The Astute140 Meter is a bench-top/tabletop analyzer that converts the fluorescent signal from each of the two biomarkers assays, TIMP-2 and IGFBP-7, contained within the test cartridge into a single numerical result.

The NephroCheck Test results are available on the Astute140 Meter in approximately 20 minutes.

The Astute140 Electronic Quality Control (EQC) Device

The EQC procedure verifies the calibration of the Astute140 Meter to confirm that the meter is functioning properly, including the following meter systems: positioning system, optic system and other internal systems.
